基于DSP和CPLD的一种429总线卡的设计

Design and application of card of bus ARINC429 based on DSP and CPLD

在对航空相机多项性能进行检测的系统中,必须实现通用计算机接口与航空相机ARINC429总线之间的数据传输.给出了一种基于DSP芯片TMS320F2812和CPLD芯片EPM7064设计的RINC429总线通讯卡的软硬件设计和实现方案.并通过实践验证了该板卡能够完成总线数据格式转换和数据传输,完全满足对相机多项性能检测的要求.

In the performance monitoring system of an aerocamera, it has to come through the communication between the test computer interface and the aerocamera one. In this paper , a new ARINC429 bus communication-card based on the DSP and CPLD technique is designed, and the design of software and hardware are introduced. By practicing, this card can accomplish the data style transduction and communication, exactly satisfying the demand of the performance monitoring system of aerocamera.
